In reply to GarethSL:
A bit of what he said. You won't find anything more than a credit course on snow-pack dynamics on an undergraduate course, and that's if you're lucky - its a niche specialty. For example, I teach a little (about 30 mins worth) as part of a second year course on the entire cryosphere, and none is included in its third-year equivalent module. If you're interested and don't have a relevant undergraduate degree, I suggest a BSc in Geography or Physical Geography, and then do a snowpack related dissertation.
Masters level courses may start to get to this level of specialisation, although again I would expect them to be more generalised - for example my institution previously offered a Glaciology MSc, which would include scope for a snowpack-based research thesis. Alternatively, if you find one, an MRes or and MPhil might get you access to greater opportunity to look into snowpack stability science. Note that you will of course need a (good) Geography undergraduate degree to be able to access masters-level courses in most cases.
Whilst GarethSLs UNIS recommendations are great, only AG346 really links with your interests - and you will need to be working towards a masters level qualification to get on it. My experience of UNIS courses (from the teaching side) is that they are often markedly over-subscribed.
If you have any Qs you don't want aired in public, feel free to drop an email my way.
